I have manufactured what you are after. I used ballscrews because you
can get more control of movement and thus make a more accurate cut. I
used stepper motors and have had good results but if you want to change
speeds during a cut say for corners and such then servos which cost a
lot more may be worth a look. There is a plasma cutter on Ebay NEW
POWERMAX 1100 PLASMA CUTTER Item #225452656 that runs on single phase or
three phase that works well and will cut up to 1".

Dave has a complete kit on this. As well there is a windows based
program called Flash cut CNC that has steppers or servos and the demo
looks real nice. Price is the key factor if you build a cheep system
thats what you get if you want all the toys you pay more for it..
I have one such unit for sale if interested.
